BEET-PLOW.

Speccaton of Letters Patent.

Patented Nov. 23, 1915..

Application filed May 29. 19414. Serial No. 839,736.

the main object of the invention is to provide a novel means for raisingand lowering the plow-carrying frame with relation to the supportingwheels, thus permitting the plows to be adjusted to cut deep or shallowas circumstances may require.v

Further objects will hereinafter appear.

rl`he invention consists of the parts and the construction andcombination of parts as hereinafter more fully described and claimed,having reference to the accompanying drawing, in which the figure is aperspective of the invention.

Referring to the drawings, A indicates the main frame of the plow, whichis carried by front and rear wheels 2 and 3 respectively. The frame ishere shown as consisting of a central beam 4, to which is secured inspaced relation, by cross-bars 5, a pair of beams G, the rear ends ofwhich are slightly expanded, as at 7, to form a support for a ridingseat S and rear axle 9. The rear axle is loosely journaled in the frame,as at 10, and is provided with crank-like extensions 11, upon the outerends of which the rear wheels 3 are journaled.

Suitably secured to one side of the rear frame extension is astationary, semicircular rack bar 12, and secured to the rear axle 10,as at 13, is a lever 14, provided with a spring-actuated pawl 15 whichis adapted to interlock with the semicircular rack bar 12. The pawl 15is operated bv va handle and link in the usual manner. rlhis rearlifting attachment comprising the construction of the rear axle uponwhich the wheels 3 are mounted, together with the provision of the lever14 with connected rack bar 12, permits the axle to be turned withrelation to the frame, and consequently raises kand lowers the framewith relation to said wheels.

Suitably secured to the front end of the frame, as 'at 16, is an offsetcross-bar 17, and similarly secured to the lower side of the frame, justbelow the cross-bar 17, is a secondary bar 18. Extending through saidbars, on each side of the frame, is a pair of vertically disposed rods19, the lower ends of lwhich are fork-shaped, as at 20, to form journalsfor the front wheels 2. Connecting the upper ends of said rods is across-bar 21,V and plvotally connected at 22 to an inverted'shaped,upright mounted on said bar, is a leverr23, one end of which isprovided with a pawl 241 and an operating grip, said pawl being adaptedto interlock with a semicircular rack bar 25 and having a housing whichslidably receives and is carried by the latter. Connecting the outer endof said lever with the front end'of the frame is a link 26. Theprovision of the lever 23, in `connection with link 26, provides a frontlifting attachment and means by which the rods 19, with connectedcross-bar 21, may be raised 0r lowered with relation to the frame j A;or, in other words, provides a means whereby the front end of the'framemay be raised or lowered with relation to the front wheels 2. Both ofthese attachments are within the ready control of the operator on theseat 8.

The steering of the beet plow is accomplished in this instance bymounting a cross arm 27 on the inner end of a clevis indicated at 28,and connecting the outer ends of said arms, by means of rod links 29,with a footactuated steering bar 30, pivotally mounted, as at 31, upon aslightly elevated extension bar 32 secured on the center post of theframe. A machine constructed and arranged in the manner here shown canbe easily handled as the levers 14 and 23, by which the adjustment ofthe frame, with connected plows 33 and 33, is accomplished, aresuiiicientlylong to make this adj ustmenteasy. The steering and handlingof the plow is otherwise accomplished directly from the riding seat, asthe operator will only have to swing the steering bar 30 by means offoot extensions 34 formed thereon.

The wheels 2 are in this instance trailer wheels, although they aremounted on the forward end of the plow-supporting frame. The'rods 19 areso mounted that they may turn freely in any direction both in bar 21 andthe guide bars 17 and 18. This permits the wheels 2 to act as trailerswhich Vwill llo perienee and judgmentof the manufacturer may dictate.

I also Wish it understood that various changes in form, proportions andminorv details oi construction may be resorted 4to l within the yscopeof the appended claim and lthat do notvvish vto Zlimit v'myself to thespecific 'design and 'construction here shown.

'Having thtis described my .invention,'ivhat I AClai'mfand` desire tosecure by Letters Pat- In combination `with l a lframe 'having v'Wheels' lat its rear, a' siipport` for thle'ront enidof the iframecomprising` a pair'bf Wheeled vertical standards,` a' connection betweenlsaid stanilards,"amlovver cross-bar secnredto the 'frame on itsunderv'facdman lip- Coipiesof this patent may be obtained-1-for percross-bar secured to the frame on its top face vand having its endsoffset upvvardly, the ends of said cross-bars having alined apertures inwhich said standards slide, an inverted V-shaped upright on saidconnection between the standards, a lever pivoted between its ends tosaid upright, an arc-shaped rack bar secured at its lower end to Atheframe, a pawl having a housing which latter slidably receives the rackbar and is carried by the lever, means to operate the pawl, anda linkpivoted 'to the front end of the frame 'andto 4the front end of lSaidlever,
